Alloyed tool steel

Alloyed tool steel

General characteristics

Alloy steel is an alloy of iron with molybdenum, cobalt, vanadium, tungsten and others elements, which at a certain way of processing and production give the material the required characteristics and structure.

Marking

The main alloying elements are identified by the following letters: B — niobium, G-manganese, — tungsten, D — copper, cobalt, E-selenium, M is molybdenum, X — chrome, P — phosphorus, N-Nickel, P — CE, T — titanium, s — silicon f — V, C — Zirconia, s — aluminium. The numbers that are after the letters denote the rounded content of these elements. When the content of the element is less than 1.5% figure for the letter index is not assigned. Additive carbon is specified at the beginning of the brand hundredths of a percent (for structural steels) or tenths (of the steels).

Production

Alloy tool steel is produced according to GOST 5950−2000. This standard normalizes the production of strips, rods, coils hot rolled, forged, calibrated with special surface treatment of tool and alloy steels, the percentage of grades 4KHMNFS, 3KH2MNF, 9ХФМ in the form of forgings, bars, strips, billets, pipes and other metal products.
